Using suction you have the possibility of damaging your sight, brain, and hearing. One of those bulbs they use on a baby are not likely to hurt you. A vacuum cleaner is not something you should try. A Doper did something similar last year and was lucky.

Due to genetic and occupational factors I have been seen by an otolaryngologist many times in my life. Examinations often involve what seems like the use of a vacuum; when the device is inserted in the mouth and the nostrils pinched together, a sensation is produced akin to having one's skull pulled through a straw. By which I mean painful, though of short duration.
Seeing an Ear Nose and Throat physician is strongly recommended, your wife may have congenital formations remediable to good, long lasting effect.
